DUPLEX SELF-CLOSING FAUCET.

SPECIFICATION forming part 0f Letters Patent NO. 535,468, dated. March12, 1895. Application iiledAugust 25, 1892. Serial No. 444,077. (Nomodel.)

.To all whom it mag/concern.-

Be it known that I, HARRY S. TEAL, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Inlprovements in Duplex Self-ClosingFaucets, of which the following is a full, clear, and eX- actdescription, reference being had to the accompanying drawings, forming apart of this specification.

My invention relates to that class of faucets which are designed toenable water of different temperatures (as hot and cold) to be drawnseparately through a single outlet, by manipulations of a singlevalve-actuating spindle, and more particularly to such faucets as are soconstructed that when the handle is released, the spindle shall beautomatically returned to its intermediate position, so as to enableeither valve to automatically close; thus preventing waste of water, andadapting the valve for use in situations (such as in railway cars,steamboats, and the like) where but a limited supply is obtainable. A

Among the primary objects of my invention is included that of producingaself-closing duplex faucet the valve-closing and spindle-returningsprings of which shall be wholly isolated from contact with wateriiowing through the valve-casing; thereby avoiding all possibility ofsuch injury to the springs by the water. as will cause the springs tofail in their work, and consequently permit the Water to be wasted.

A further primary object of my invention is to produce a faucet which,in addition to the advantages above enumerated, shall be simple, compactand durable in construction, capable of being readily placed in positionand removed therefrom without necessitating any disorganization of theprincipal parts of the faucet, and the casing of which shall be soconstructed as to permit ready access to the operative parts of thefaucet, for purposes of inspection, repair, and thelike.

To the above purposes, my invention consists in certain peculiar andnovel features of construction and arrangement, as hereinafter describedand claimed.

The more precise nature of my invention will be better understood whendescribed with reference to the accompanying drawings, in which* Figurel is a central vertical section ot' a faucet embodying my invention; theplane of the section being indicated by the line 1-l ofFig. 3, and thedirection of view being that indicated by the arrows upon said line.Fig. 2 is a vertical section of'the faucet, taken on the plane indicatedby the line 2-2 of Fig. 3; the direction of view being that indicated bythe arrows applied to said line. Fig. 3 is a horizontal'section of thefaucet, taken on the plane ot' its valves. Fig. d is a detached View, incross-section, and also enlarged, showing `one of the Valves and certainof its im` mediate attachments. i

. In the said drawings,D designates the casing of the valve, this casingbeing formed with two transverse partitions or septums F and F extendingat right angles to each other andfrom the bottom of the casing to itstop'. The partition F forms, between itself and the rear wall of thecasing D, an outlet-chamber dzwhich extends from bottom to top of thecasing, and also from` side to side thereof, while thepartition Fextends from vthe front Wall of the casing D to the partition F andforms, between itself and the sides of the casing, two inlet chambers dand d; these inletchambers also extending from bottom to top of thecasing.

The chamber d may be the hot-Water chamber and the chamber d may be thecold-water chamber, and such waters are delivered into said chambers bytwo supply-pipes F2 which lead from suitable sources of water, and whichare connected by suitable couplings, such as O, to nipplesfand f pendent1 from the bottom of the casing D.

Communication is established between the,

IOO

connected (as by a coupling O) the lower end of a discharge pipe ornozzle C; the upper end of said nozzle being shown as bent forwardlybeneath the top A of the receptacle.

Two brackets or lugs 5 and 6 project horizontally rearward from the rearwall ofv the casing D and in said brackets is journaled a Verticalrock-shaft Z which carries a double horizontal rockarm M; the shaft Zbeing shown as polygonal in cross-section where it passes through themiddle of the rock-arm M, so that said rock-arm shall always oscillatewith the rock-shaft. At its ends the rock-arm M carries two rollers mwhich engage the rear ends of the two Valve-stems H and H', to behereinafter more fully described, and at its upper end the rock-sha`ftlis inserted removably into the lower end of a sleeve N; the enteringend o f the rock-shaft being polygonal in cross-section, so that therock-shaft shall always oscillate with the sleeve, and a shoulder orenlargement L at the upper end-portion of the rock-shaft serving tosupport the sleeve. Into the upper end of the sleeve N is removablyinserted the' lower polygonal end of a vertical spindle E, which extendsupward through the top A of the receptacle, and which carries a suitablehandle B at its upper end; the lower end of the spindle being heldremovably within the vupper end of the sleeve N by a set-screw n, andthe upperend of said spindle being provided with a retaining-nut R,while the upper end-portion of the spindle turns in a rearward offset 9of the upper endportion of the discharge-nozzle C.

The casing D is supported in its required position beneath the top A ofthe receptacle, by a pair of hangers P the upper ends of which aredetachably secured to the offset 9 and the lower ends of which are alsodetachably secured (as by screws, or equivalent devices) to the sides ofthe casing D. It will thus be seen that the entire casing D and itscontained parts may be readily'detachedfrom the top of the receptacle,simply by detachingthe ends of the hangers P from the sides of thecasing D, disconnecting the couplings O and O and loosening theset-screw n, and that said casing D may be as readily replaced by simplyattaching the ends of the hangers P to the sides of the casing,connecting the couplings 0 and O,'aud tightening the setscrew n.

The fronts of the two inlet-chambers d and d are formed by two nuts 7and 8 which are screwed into the front wall of the casing D, and withinsaid chambers d and d respectively are located the outlet-valves G andG; said valves finding their seats in the front sides of theValve-openings 2 and 3 in the partition F. These valves G and G arecarried upon the front ends of two valve-stems II and H respectively.These valve-stems H and H extend horizontally through the partition Fand also through theoutlet-chamber d2, and the rear wall of the casing,and said stemsare of such length as to protrude rearwardly from saidrear wall of the casing a sufficient distance to come into contact, attheir rear extremities, with the rollers 'm at the extremities of thedouble rock-arm'M, when said arm is in its intermediate or normalposition.

Upon the rear wall of the casing D are screwed two stufing-boxes I and Ithrough which extend respectively the stems H and H said stems beingtightly packed into the stuffing-boxes so as to prevent leakage at thesepoints.

The rear end-portions t' and 1I of the stuffing-boxes I and I',respectively, are hollow, and within the cavities thus form ed areplaced spiral returning-springs J and J which surround the rearend-portions ot' the valvestems H and H respectively; said springs beinginterposed between the front ends of the cavities and heads orenlargements K and K upon the rear extremities ot' said valve,

stems, and the springs acting against said heads or enlargements to seatthe valves G and G in the valve-openings 2 and 3. The 'arrangement issuch that the springs J' and J are Wholly isolated from the water whichflows through the valve-'casing D, so that such water cannot possiblyproduce any corrosion of said springs. Furthermore, the springs .I and Jare suiiiciently exposed to be readily accessible for adjustment and canbe readilyr inspected Whenever desired. The caps 7 and 8 also enable thevalves G and G' to be readily inserted into and removed from thevalvecasin g, inasmuch as upon the removal of' such caps, the valves canbe readily so manipulated. In order to insure tight closing of thevalve-openings 2 and 3 by the valves G and G', each of said Valves isprovided with asoft facing f2 as in Fig. 4, secured. to the valve bymeans of a retaining-ring G3 provided with an inwardly extending liangeor shoulder g2 for overlapping the outer edge of the facing. Theretaining-ring G3 is threaded upon the valve, and each valve is securedto its spindle by means of jam-nuts h which are screwed upon theexternally screw-threaded and re duced front ends of the stems; the softfacings f2 being held between the resulting shoulders of the valve-stemsand the rear faces ofthe valves. Thus all liabilityy of the softfacingsto detach themselves from the valves when the latter are opened,is, avoided, and consequently there will be no sticking of the facingsin th'evalve-seats and no obstruction ofl the flow of water. Obviously,the described relation of the valves and their stems may be reversed, ifdesired, the stems in such event entering the valves from the frontinstead of from the rear, and the jam-nuts h serving then to retain thefacings in place.

Having thus described my invention, what I claim as new therein, anddesire to secure by Letters Patent, is-

A self-closing duplex faucet, comprising a IOO casing containing aplurality of valves, stems forl said valves extending througbthe wall ofthe casing, a two-part oscillatory spindle having a, detachable couplingfor its parts and carrying a double rock-arm the ends of which engagethe ends of the Valve-stems, return ing-springs external to the casingand each surrounding one of the Valve -stems, inlet- `pipes detachablycoupled to the casing, and a discharge-nozzle also detachaloly coupledto Io the casing, and hangers detachably connected to said casing,substantially as set forth.
